Lock-,SPINDLE FoR SAFES.

Ll-PEGFICATION forming part of Letters Patent No. 341,563, dated May 1l,1886.

Application filed February 5, 1886. Serial No. 190 910.

To all whom it may concern.-

Be it known that l, JACOB DYER, a citizen of the United States, residingat Canton, in the county of Stark and State of Ohio, have inventedcertain new and useful Improvementsin Lock-Spindles for Safes; and I dohereby declare that Vthe following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specilication, and to the letters and iigurcs ofreference marked thereon, in which- Fignre l is a perspective view oftheplates that hold the gear-w heels for driving the combination-shaft andthe lock-bar shaft. Fig. 2 is a perspective View showing the parts inposition to be placed together. Fig. 3 is a longitudinal section of asafe-door with my improved spindle mechanism in position. Fig. 4 is aperspective view of a safe-door, showing the outward appearance of thespindle; Fig. 5', detached views of the metallic rings and the flexiblewasher.

The present invention has relation to lockspindles for safes; and itsnature consists in the different parts and combination of partshereinafter described,and particularly pointed out in the claims.

Similar letters of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, A represents a tubularcombination-spindle, which may be substantially of the form shown in thedrawings, the inner end of which is provided with the cog-wheel a, whichmay be formed integral with the spindle A, or it may be formed separateand attached in any well-known manner. The forward face or surface ofthe cogwheel a is provided with the collar or flange a', whichcorresponds in depth with the surface-plate I), and is for the purposeof provid-I ing a suitable bearing for the combinationspindle A. Theinner end of said combination-spindle is also provided with the annulargroove b', which is located substantially as shown in the drawings, andis for the purpose hereinafter described.

rlhe combination-spindle A is formed hollow, as shown in Fig. 3, and isso formed to receive and hold the lock-bar spindle B, as shown in saidFig. 3.

(Model. l

The cog-wheel lC is located substantially as show n in the drawings, andis rigidly attached to the combination-shaft c. These wheels a and C areso arranged that they will mesh toA gether, and thereby communicatemotion from the combination spindle A tothe combinationshaft c. Saidwheels a and C are both located in the recessed lock or plate D.

The lock-bar spindle B is substantially of the form shown in thcdrawings, and is provided upon its outer end with the cog-wheel d. Uponthe outer face or surface thereof is located the annular tongue d',which enters the groove b. Between the lower end of the spindle B andthe 'tongue d are located the metallic rings or bands c and the flexiblewasher e', the metallic rings or bands being for the purpose oflessening the friction, and the fiexible washer being for the purpose offorming a perfect air-tight connection between the combination -spindleA and the lock-bar spindle B.

To the backof the wheel a is placed the an-Y nular disk E, which may besubstantially of the form shown in the drawings, and is placed in theblock or plate D, and so arranged that the ledge E will be ush with theinner surface or face of said block or plate when the same is-placed inproper position. This disk E is for the purpose of separating the wheelsa and d, and also for assisting in holding said wheels in properposition, and at the same time separating the cogs of such wheels, sothat their movements will be entirely independent of each other. Y

W'hen the wheel a., together with the combination-spindle A, has beenplaced in proper position, the metallic bands or rings e and the iexiblewasher e are then placed in their proper positions and the disk Dproperly located, when the lock-bar spindle is passed through the hollowcombination-spindle A, thus bringing the cog-wheel (l in properposition, said parts being located and arranged substantially as shownin Fig. 3. The plate or block F is then placed against the plate orblock D, as shown in the drawings, and is so arranged that the wheel dwill mesh in the wheel f, which communicates motion to the lock-barshaft g.

It will be seen that all the bearings for the combination-spindle A andthe lock-bar spin- ICC dle B have one common center, which enables theplates or blocks D and F to be placed at any desired angle withreference each other, and thereby change the position of such blocks orplates in different safes, and at the same time I am enabled to operatethe combinationshaft and the lock-bar shaft through but one aperture inthe door of a safe, thereby lessening` the possibility of insertingexplosives.

In placing my improved spindles in a safedoor the plates which are toreceive the plates or blocks D and F are provided with openings orcut-away spaces to receive said plates or blocks, the location andangles of the openings or spaces being arranged with reference tothedesired angle of such blocks or plates.

In case it is desired to change or Vary the distances between thecombination-shaft c, the lock-bar shaft g, and the spindles A and B,idle-wheels may be placed between the Wheels communicating motion to theshafts c and g.

The inner end of the lock-bar spindle B is provided with the conical endhf, which its into a corresponding recess in the plate fitting againstsaid conical end, and is so arranged to prevent the end of the spindle Bfrom being injured by heavy blows upon the outer end of Said spindle.

It will be seen that the spindles A and B can be operated independent ofeach other.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The combination, with the combinationspindle A and the lock-barspindle B, one located within the other, and their bearings having acommon center, of the blocks or plates D and F, each of said blocks orplates being provided with gear-wheels for communicating motion to thecombination-shaft and lock-bar shaft, substantially as and for thepurpose specified.

2. The combination, with the combinationspindle A and the lock -barspindle B, one

working 'Within the other, and provided, respectively, with groove b andtongue d, of the metallic rings e and flexible washers e', placedbetween the lock bar spindle and tongue, substantially as described.

3. The combination, with the combinationspindle A, provided upon itsinner end with cog-wheel a, of the combination-shaft c, having thecog-wheel C rigidly attached thereto, the block or plate D, andthelock-bar spindle B, substantially as described. A

4. The combination, with the lock-bar spindle B, provided with cog-Wheeld, of the lockbar shaft y, having a cog-wheel, f, rigidly attachedthereto, the block or plate F, and the combinationspindle A,substantially as described.

5. The combination ofthe combination-spindle A,'having cog-wheel a, thelock-bar spindle B,"having cog-Wheel d, the combinationshaft c, havingcog-wheel C, the plate D, for receiving the Wheels a and U, the lock-barshaft g, having cog-wheel f, the plate F, for receiving the wheels d andj', and the annular disk E,-for separating the wheels a and d,substantially as described.

6. The combination, with the inner and outer safe-door plates and thecog-receiving plates D and F, of the combination-spindle A, havingcog-wheel a, the lock-bar spindle B, having a cog-wheel, d, providedwith a conical center, h, stepped in one of the door-plates, and thecombination-shaft c and lock-bar shaft g, each having cog wheelsreceiving motion from the cog-wheels of the spindles, substantially asdescribed.

In testimony that I claim the above I have hereunto subscribed my nameinthe presence of two witnesses.

JACOB DYER.
